A deadly assault has resulted in murder charges after a roadside stabbing shortly before midnight September 9, police say.

Manuel Ignacio Iracheta, 20, was killed in the 8000 block of the North Freeway after an altercation grew violent, HPD says.

Octavio Daniel Figueroa, 23, has been charged with murder in the incident.

A Harris County Sheriff's Office deputy witnessed much of the event, HPD says. The deputy "observed an accident scene that escalated into an assault," police say. "The deputy detained several people and later saw the victim breathing heavily on the ground. The victim appeared to have been stabbed in the chest."
